Description
Technical field
This utility model relates to a kind of control valve and uses the continuous transfer pump of this control valve, lifting device for liquid.
Background technology
At present, in the liquid such as oilfield exploitation and thermal cycle is exploited, the mode of suspending weight is generally used to balance the counteracting force that fluid column acts on positive displacement pump, in oilfield exploitation, oil extraction pump is by the way of hanger hangs, it is fixed on pit shaft, during to ensure that fluid is upwards lifted by oil extraction pump, fluid acts on the hydraulic coupling upwards on oil extraction pump, need to balance with the deadweight of oil extraction pump and residing flow string thereof, increasing along with oil production, the weight demands of flow string is improved the most therewith, there is, by making flow string, the problem that weight is excessive in this, it is unfavorable for going into the well and tripping out of tubing string, oil recovery preparatory stage and later stage upkeep operation are wasted time and energy.Meanwhile, oil suction when plunger oil extraction when upstroke that traditional plunger oil-well pump mostly is in unidirectional oil pump, i.e. oil well pump, down stroke, the fluid that such oil well pump is discharged by the way of interruption at oil Bottomhole pressure, cause the efficiency of oil producing operation to reduce.
nullChinese patent literature CN200968202Y discloses a kind of hydraulic oil producing device，The hydraulic power supply connected by power fluid pipeline including the upper end of bidirectional hydraulic pump and hollow rod thereof，Bidirectional hydraulic pump is plunger type continuous transfer pump，Bidirectional hydraulic pump include pumping cylinder and in the piston rod that is coaxially disposed，The two ends up and down of piston rod are equipped with the piston being slidable in the vertical direction being assemblied in pumping cylinder，Upper cover of piston rod is equipped with the return of stroke valve of the position combined closely in pumping cylinder between two-piston，And pump discharge valve and lower pump discharge valve it is sequentially arranged at intervals with from top to bottom in the upper end of the upper pump chamber of pumping cylinder，The port of export wherein going up pump discharge valve connects with oil pipe，The port of export of lower pump discharge valve is communicated with the lower pump intake valve being in lower pump chamber lower end，The arrival end connection of upper pump discharge valve is in the upper pump intake valve below lower pump intake valve，One passage of each valve weary power fluid outlet side connection return of stroke valve，The outlet side connection oil pumping oil pipe of bidirectional hydraulic pump.In use, power fluid is after the hydraulic pump of hydraulic power supply pressurizes, enter in return of stroke valve by hollow rod, upward pressure chamber between a passage entrance return of stroke valve and the upper piston of return of stroke valve, promote upward pressure chamber up, the volume of upper pump chamber reduces, so that crude oil is in upper pump discharge enters oil pumping oil pipe in upper pump chamber；Now lower piston is also up under the drive of piston rod, the volume making downforce chamber diminishes, the crude oil that the weary power fluid of downforce intracavity is lifted by another passage of return of stroke valve and bidirectional hydraulic pump is integrated, continue lifting, the volume of this pump chamber at present is gradually increased, pressure is gradually lowered into negative pressure, oil well Crude Oil is progressively drawn in lower pump chamber by lower pump intake valve, until upper piston and lower piston go upward to top dead centre, the thrust of piston on the lower, promote the commutation of return of stroke valve, in change, the high-low pressure interface in downforce chamber, downforce chamber is made to become high pressure chest, thus along with lower piston drives piston rod, during upper piston is descending, lower pump chamber Crude Oil is discharged together with power fluid weary in upward pressure chamber.But this bidirectional hydraulic pump not only needs arrange entry and exit valve at the two ends of pumping cylinder, but also need the most supporting return of stroke valve, wherein any one damage all can make whole bidirectional hydraulic pump the problem that cannot work occur, and causes whole bidirectional hydraulic pump to there is the problem that structure is complicated, fault rate is high.Simultaneously, the oil return pipe of this bidirectional hydraulic pump medium power liquid and the oil exit pipe of crude oil are oil pipes, this allows for draining back to, from oil pipe, the mixed liquor that the liquid of fuel tank is power fluid and crude oil, so in the case of power fluid is not crude oil, crude oil is easily polluted by power fluid, increases difficulty and the energy consumption of crude refining.
